I've found that some people in society work with their hands, and other people type on computers. For the latter, there will always be contractors. Internet DIY forums will do nothing to change that, mostly because some people are incapable of, say, pouring a concrete pad or wiring up a light switch.
People that work with their hands are too stubborn to call a contractor anyway, so that point is moot.
So for the cell phone salesmen and venture capitalists, "Hi, my name is Scott, how may I help you with your project today?"
